IMPBOVED sNoW-PLGUGH.

To ALLWHOM 1T MAY concourt:

Be it known that I, CHARLES LusTED, of thecity, county, and State of New York, have invented a new and improved Snow-Plough; and I do hereby declare that t-he following is a full, clear, and exact description thereof, which will enable others skilled in the art to make nud u s'e the saine, reference being had-:to the accom.- panying drawings, forming part of this specification, in which- Figure 1 represents a longitudinal sectional view of my invention, the plane of section being indica-ted the linea x, fig. 2.

Figure 2 is a plan o1 top view of the same. 1

Figure 3 is a side elevation, on a reduced scale, of the sainet Similar letters of reference indicate corrlesponding'parts.

This invention relates to a new plough 'for clearing railroad-tracks from snow, and consists in the use of an oscillating p loughshare, which throws ofi' the snowthat has been raised by it, so as to-prevent the accumulatipn ofthe snow upon th'e share. .The oscillating share is hinged to a stationary lower share, and is connected with n crank` on the' uxie of the truck, to which the device is secured. By means of a clutch-arrangein'ent, the con-y nection between the axle and the share may be established or interrupted at will', so that the upper hinged share may remain stationary, if desired. l

A representsa truck, of suitable construction, mounted upon wh'eels in th ordinary manner, and arranged so thatit can be secured to a train or locomotive, to clear the track in front of the saule. On the front axle B, or-on anyone of its. axles, are hnng cranks, a a, which turn loose on the axle, but which can be made to -revolve with thesame'hy means of clutches, Zz b, fitted to levers c c, as shown. The levers are hinged to the track, and ure operated by means of an oscillating lever, d, and intervening connecting-rods, c, or by any other suitable mechanism.

C is a metal ploughshare, secured.v firmly in front of the truck A, its most forward point being at one side of the apparatus, as shown-in fig. 2 To the upper edge of this share C is hinged, by means of hinges j, another share, D, 'which forms a continuation ofthe former, so that the shares C and D do ac tually form but one single share of suitable height, and as wide as the road to be clearedlis to be. Y

To the inner side ofthe hinged share D are secured lugs, ff, to-which jointed connecting-rods g are pivoted, the lower ends of which are pivoted to the cranks'a a, as is clearly shown in iig. 1.

When the-*cranks are' thrown in gear with the clutches, and when the truck is n'ioving, the share D will thus be oscillated around its pivot, the extremes of its position being indicated inA iig. 3by red and black' lines.-

Thus, as the truck is pushed through the snow, the latter will rise on the share C D, and would accumulaote thereon., preventing the further progress of the truck, it' the share D would not, once during every revolution of the axle B, swing forward, thereby not only throwing off the snow that had accumulated on it, but' also casting it aside, owing to the oblique position of the share. The track will thus be etfectually cleared from the snow, and it will require comparatively little power to force the truck ahead.

The`snow-ploughs now in use :are ineffective -i'n heavy snow, as they raise thesnow without casting it aside, while those snow-ploughs which m'elt the snow glaze the rails in such a manner that they are unsafe 'for useas long, as the ice remainsupon them. A I

To thev sides of the share D are secured anges, la 7L, which fit over the side plates c-'ot` the truckJ to close the opening between thefrontl end of these plates and the share D, when the some is swungr forward. The snow is therebyprevented from falling upon the working-mechanism of the truck.

For singletrack roads, the share C may be made pointed, that is, with its forward partin the centre, sons to throw the snow to both sides.A vIn that ease, the share D must De-composed of two pieces, which meet in the centre. V

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-f- 1. The hinged oscillating ploughshareD, when made and operating substantially as and for the purpose Aherein shown and described.

2. A snow-plough, provided with an oscillating share, D, which is hinged to the upper edge ofa stationary share, C,a'nd which has angesLt, at the ends, substantially as herein shown and described.

3. The hinged share D of a snowlplough, connected by means of a jointed rod'or rods, g, with a crank orv cranks, at, on the axle of the,ploughitruck, as described, the crank or cranks being loose onthe axle, and con nected with clutches, so that the share can be iade to oscillate or not, as setforth.
